`TP_INTSET_ITER_INIT` is deprecated and should not be used in newly-written code.

since 0.19.0. Use TpIntsetFastIter instead

A suitable static initializer for a TpIntsetIter, to be used as follows:

    1
    2
    3
    4
    5
    6

    void
    do_something (const TpIntset *intset)

### tp_intset_iter_init ()

    void
    tp_intset_iter_init (TpIntsetIter *iter,
                         const TpIntset *set);

`tp_intset_iter_init` is deprecated and should not be used in newly-written code.

since 0.19.0. Use TpIntsetFastIter instead

Reset the iterator `iter` to the beginning and make it iterate over `set` .

#### Parameters

iter | An integer set iterator to be initialized. |
set | An integer set to be used by that iterator |

### tp_intset_iter_next ()

    gboolean
    tp_intset_iter_next (TpIntsetIter *iter);

`tp_intset_iter_next` is deprecated and should not be used in newly-written code.

If there are integers in (`iter->set` ) higher than (`iter->element` ), set (iter->element) to the next one and return `TRUE`. Otherwise return `FALSE`.

Usage:

    1
    2
    3
    4
    5

    TpIntsetIter iter = TP_INTSET_INIT (intset);
    while (tp_intset_iter_next (&iter))

since 0.19.0. Use TpIntsetFastIter instead

Reset the iterator `iter` to the beginning. It must already be associated with a set.

#### Parameters

iter | An integer set iterator to be reset. |

## Types and Values

### TpIntset

    typedef struct _TpIntset TpIntset;

Opaque type representing a set of unsigned integers.

Before 0.11.16, this type was called TpIntSet, which is now a backwards compatibility typedef.

### TP_TYPE_INTSET

    #define TP_TYPE_INTSET (tp_intset_get_type ())

The boxed type of a TpIntset.

Since: 0.11.3

### TpIntsetFastIter

    typedef struct {
    } TpIntsetFastIter;

An opaque structure representing iteration in undefined order over a set of integers. Must be initialized with `tp_intset_fast_iter_init()`.

Before 0.11.16, this type was called TpIntSetFastIter, which is now a backwards compatibility typedef.

Usage is similar to GHashTableIter:

    1
    2
    3
    4
    5
    6
    7
    8
    9

    TpIntsetFastIter iter;
    guint element;

    tp_intset_fast_iter_init (&iter, intset);

    while (tp_intset_fast_iter_next (&iter, &element))
    {
      printf ("%u is in the intset\n", element);
    }

Since: 0.11.6

### TpIntsetIter

    typedef struct {
        const TpIntset *set;
        guint element;
    } TpIntsetIter;

`TpIntsetIter` is deprecated and should not be used in newly-written code.

since 0.19.0. Use TpIntsetFastIter instead

A structure representing iteration over a set of integers. Must be initialized with either `TP_INTSET_ITER_INIT()` or `tp_intset_iter_init()`.

Since 0.11.6, consider using TpIntsetFastIter if iteration in numerical order is not required.

Before 0.11.16, this type was called TpIntSetIter, which is now a backwards compatibility typedef.

#### Members

const TpIntset *`set`; | The set iterated over. |
guint `element`; | Must be (guint)(-1) before iteration starts. Set to the next element in the set by `tp_intset_iter_next()`; undefined after `tp_intset_iter_next()` returns `FALSE`. |
